Coils of Magnetic Field Lines
Coils of Magnetic Field Lines
A smallish solar filament looks like it collapsed into the Sun and set off a minor eruption that hurled plasma into space (June 20, 2017). Then, the disrupted magnetic field immediately began to reorganize itself, hence the bright series of spirals coiling up over that area. The magnetic field lines are made visible in extreme ultraviolet light as charged particles spin along them. Also of interest are the darker, cooler strands of plasma being pulled and twisted at the edge of the Sun just below the active region.

Wide field view of the sky around the young star HL Tauri
Wide field view of the sky around the young star HL Tauri
This image shows the region in which HL Tauri is situated. HL Tauri is part of one of the closest star-forming regions to Earth and there are many young stars, as well as clouds of dust, in its vicinity. This picture was created from images forming part of the Digitized Sky Survey 2.
